Do I need planning permission to change my windows?

The planning rules covering windows are covered in this section on the Planning Portal¹.

If, after using our site guidance, you have further questions about a particular aspect of planning permission you should contact your local planning authority, usually your council. Our Service Desk aren’t planning experts so you will need to talk to your local authority planning team.

You can find contact information for your local planning authority on the Planning Portal:
